Ubuntu Security :: Secure P2p Instant Messaging

Feb 5, 2011

Is there a program already set up to do this? Probably similar to WASTE (URL...), though waste's client is currently unsupported on the newest version of ubuntu (make error having to do with char* or something). Preferably windows and linux supported. Another thing that could be of use would be a local ssh chat. For example someone connects to my box either as me or as another user and runs 'hiben' and a window (or i ran a command or something and have a window open for it) pops up that we can chat in. Something other than single line messages.

Server :: Email Content Filter Rules For Either Postfix

Feb 3, 2010

I want a mail server that can work just like MDaemon. The reason is, I want to have an email content filter rule that does some thing like this.

1. If the To Header contains "support@thisdomain" then run a program.
What this means is that, there is a program here in the office, and if some one sends an email to the support address, with an attachment of .exe and that person is a customer, then the program should be run. The only thing I need here is if there is a rule or script that can filter email header and run a program.

2. If the Exit Code from a previous 'Run program' rule is in the range of 1 to 100 and if the To Header contains "support@thisdomain" then send note1 "to<email address>" from <$SENDER$" "SUBJECT <AM ...>
and delete this message.

3. If the EXIT CODE from a previous 'Run program' rule is =0 and if the TO HEADER contains "support@thisdomain" then send note1 "to<email address>" from <$SENDER$" "SUBJECT <AM ...>
and delete this message.

Ubuntu Security :: Content Filter At Remote Locations?

Aug 6, 2010

We have approximately 100 retail locations that will have split vpn tunneling. Intranet traffic will flow over the vpn to the corporate headquarters, voip traffic will tunnel to a regional hub and internet bound traffic will go over the local isp. The retail locations are small with 1-8 users and no enterprise grade equipment (servers, etc). This setup in effect will render our current content filtering solution useless.

The locations will be equipped with Cisco ASA 5505 Firewalls. The original plan was to use a Websense server and the url filtering feature to act as a content filter. I just found out that pricing for Websense was not included in the budget will be a show stopper.There may also be some performance issues with this method. Putting a proxy server at each location is not really an option. We do not have the resources to place a server at each location, plus the users could simply unplug an inline device or go around it. There is minimal supervision at most of these locations.

Ideally, I would like to find a way to use something like Dansguardian with an ldap interface and the url filtering feature of the ASA firewalls. I found a program called n2h2p, but I can find 0 documentation for it. It is also 2 years old with no updates. I also need to be able totrally manage this as trying to keep up with 100 different configurations for 400 users would be virtually impossible for the amount of time I will have available

Applications :: Finding A Good Instant Messaging Client

Aug 24, 2009

I'm a Linux newbie and for my new job I have to do a lot of instant messaging to clients. They are on a variety of services, aim, icq, msn, myspace, facebook, yahoo, Google Talk, jabber, and .mac/ichat
Is there a good instant messaging client that covers most of these on one application? I am using Mandriva with KDE 4.2.

Ubuntu :: Removed Shutdown And Instant Messaging Status From Panel?

Dec 7, 2010

I booted up my laptop as usual and found that when I opened Empathy IM Client it would not allow me to login when I changed the status to Online (or equivalent). Normally as soon as I open the client the Messaging Status can be changed in the top right next to the clock so I tried to remove it but unfortunately it took the shut down panel with it.

To try and bring them back I used the restore panel commands in terminal:

Code:

$ gconftool-2 --shutdown
$ rm -rf ~/.gconf/apps/panel
$ pkill gnome-panel

Unfortunately the panels all reloaded, but without any change.

1. How can I restore the shut down and messaging section to the top panel (as is in the default)?

2. How can I get instant messaging to work again?

PS. I'm a Ubuntu noob, only installed it about 2 days ago. Thus I may need some very basic instructions to anything complicated.

EDIT: I just found the panel section was called the Indicator Applet, but now it's in the wrong place...

General :: Email Output Of Cron Command, Sends Email But No Content?

May 28, 2010

Using CentOS. I have a cron setup to run this command: Code: /var/test.sh | mail -s "Test Cron" mr182@somewhere.com The email is sent but the output of the script is not in the email body, it's just blank. I know there is some output because there are some echo statements in the script.I don't want to get an email for all cronjobs, just this one.

General :: Filter Find And Du By Content Of Inner File In Subdirectory?

May 30, 2010

I have the following command that I run on cygwin:

find /cygdrive/d/tmp/* -maxdepth 0 -mtime -150 -type d | xargs du --max-depth=0 > foldersizesreport.csv

I intended to do the following with this command: for each folder under /d/tmp/ that was modified in last 150 days, check its total size including files within it and report it to file foldersizesreport.csv however that is now not good enough for me, as it turns out inside each

/d/tmp/subfolder1/somefile.properties
/d/tmp/subfolder2/somefile.properties
/d/tmp/subfolder3/somefile.properties
/d/tmp/subfolder4/somefile.properties

so as you see inside each subfolderX there is a file named somefile.properties inside it there is a property SOMEPROPKEY=3808612800100 (among other properties) this is the time in millisecond, i need to change the command so that instead of -mtime -150 it will include in the whole calculation only subfolderX that has a file inside them somefile.properties where the SOMEPROPKEY=3808612800100 is the time in millisecond in future, if the value SOMEPROPKEY=23948948 is in past then dont at all include the folderin the foldersizesreport.csv because its not relevant to me.so the result report should be looking like:

/d/tmp/,subfolder1,<itssizein KB>
/d/tmp/,subfolder2,<itssizein KB>

and if subfolder3 had a SOMEPROPKEY=34243234 (time in ms in past) then it would not be in that csv file.so basically I'm looking for:

find /cygdrive/d/tmp/* -maxdepth 0 -mtime -150 -type d | <only subfolders that have in them property in file SOMEPROPKEY=28374874827 - time in ms in future and not in past | xargs du --max-depth=0 > foldersizesreport.csv

Networking :: ISPs Content Filter Making For Based Laptops And Workstations?

Feb 8, 2011

last friday my schools isp enabled iwsva - interscan web security virtual appliance from trendmicro. all traffic is now filtered, and slowed down. videos and other videostreams are now useless. after this we have had serious problems using our netbooks with ubuntu, and upgrading workstations with ubuntu has become very problematic, or almost impossible. i have to run the update process 6-8 times before all packages are updated.

what can i do to document the problem in a good way. the isp tells me that there are no problems, and that it has to be a linux problem. (ever heard that one before?) the ltsp-clients on my debian servers does not have the same problems, maybe because they are using the proxy on this server?

Ubuntu :: Setting Evolution Message Filter For New Email?

May 21, 2010

I have had a search for this problem, but have not found a match: undoubtedly it is so straightforward that no-one has needed to ask it before: I have two accounts in Evolution, work and gmail. I would like my work email (which I check via IMAP) to be copied locally as it comes in so that I can file it properly, but also kept on the server so that I can access through my laptop.

I have set a message filter which does the following:
Code:
IF
status is not read
THEN
set status read
copy to folder Inbox
Stop processing
The filter works (if I apply manually then it goes) AND I have set the preferences to apply filters automatically, but no joy when a new email arrives.

Server :: Potfix Email Filter Based On Sender And Recipient To Forward Messages?

Nov 2, 2010

We have MS Exchange email server with postfix/amavis on FreeBSD as proxy for anti-spam and anti-virus. We use our own developed CRM and trying to implement such functionality that when CRM manager send email to CRM client or vice versa through email client like Outlook (no plugins for CRM) this message would be shown in CRM. There is already a solution to parse emails from specific emailbox and show it in CRM.

What I need is to create postfix email filter to check if sender email is in file CRM_managers_emails and recipient email is in file CRM_clients_emails then forward that email to [URL] Filter should check both incoming and outgoing messages. I will auto generate CRM_managers_emails and CRM_clients_email files containing all such emails taken from CRM database. I know i should use something like Postfix After-Queue Content Filter but most of examples are for blocking emails.

Debian :: Update Page Content From Incoming Email?

Aug 25, 2010

I am planning an issue tracking system that I will build in Django and Python and host on a Debian server. Being an issue tracking system it will have to send and receive emails. I can easily configure the send mail functionality using python inbuilt functions. But is there a way to create new content from an incoming email?

e.g. scenario > User sends email to support@university.edu and the issue management system picks up that email (somehow) and creates a new issue based on contents of the email (preferably in real time but some delay is acceptable).

I have looked at postfix and sendmail but neither allows you create new content (issue) from an incoming email. Any thoughts?

Security :: Spam Filter Software For ISP Environment.

Jan 24, 2011

We operate a small ISP and are currently using a debian distro as our gateway server.Recently we have had an increased number of spam issues with customers (not them sending it directly, rather the customer getting infected with a virus/malware and then their computer becoming a bot).I'd like to set up another gateway of sorts to sit after our authentication gateway but before our backbone to provide spam filtering (and hopefully virus filtering) for any traffic passing through which might be email.I've tried searching for any linux based software which would suit, but I'm coming up empty.

Surely there's something already out there which can perform this task.Finally, just to clarify, I'm not talking about spam filtering for email accounts we host ourselves (this is built into our mail server); I'm talking about spam originating from customers PC's which is passing through our gateway (but not our mail server).

Ubuntu Security :: What Is Good IP Filter / Firewall Program?

Jun 10, 2010

What is a good IP filter/firewall program? Seeing as how I like free softwares, I download a lot of torrents. When I was using Windows, I used PeerBlock (the newer fork of PeerGuardian), however, it's not available for Linux. What would be a good alternative for this in Linux? I tried iplist as it has a GUI, and it was extremely buggy and blocked random web pages even after I put them on the exceptions list. And MoBlock has no GUI from I understand, nor has it been updated in years.
